Check the insulation resistance between the
photovoltaic array and ground (ground), if
there is a short circuit, the fault should be
repaired in time.
Check ac output PE wire for grounding.
Check the PV input mode
(parallel/independent mode) Settings for the
inverter. If not, change the PV input mode.
Check whether the CT wiring is correct.
Please check whether the fan 1 of inverter is
running normally.

Make sure the inverter is installed where
there is no direct sunlight.
Please ensure that the inverter is installed in
a cool/well ventilated place.
Ensure the inverter is installed vertically
and the ambient temperature is below the
inverter temperature limit.
